Are chiral theories at present describing experimental NN scattering data satisfactorily? Will the chiral approach offer a framework where fitting and selecting the existing np and pp data can be done without theoretical bias? While predictive power in theoretical nuclear physics has been a major concern in the study of nuclear structure and reactions, the Effective Field Theory (EFT) based on chiral expansions has emerged after Weinberg as a model-independent hierarchy for many-body forces and much progress has been achieved over the last decades. We review some of the issues involved which point to being close to the solution, but also that work remains still to be done to validate the theory. We analyze several examples including zero energy NN scattering and perturbative counter-term-free peripheral scattering where one would expect these methods to work best and unveil relevant systematic discrepancies when a fair comparison to the Granada-2013 NN-database and partial wave analysis based on coarse graining the interaction is undertaken.

手性核势的不确定度定量和伪造

目前，手性理论能否令人满意地描述实验性NN散射数据？手性方法是否会提供一个框架，在此框架下可以在没有理论偏见的情况下拟合和选择现有的np和pp数据？尽管理论核物理中的预测能力一直是研究核结构和反应的主要关注点，但在温伯格之后，基于手性展开的有效场论（EFT）出现了，它是一种与模型无关的多体力层次结构，并取得了很大进展在过去的几十年中已经取得了成就。我们回顾了所涉及的一些问题，这些问题都指向解决方案，但仍然有许多工作要做以验证该理论。
